Brody Jenner and Kristin Cavallari

On Tuesday's episode of "The Hills," Kristin Cavallari had some less than flattering things to say about the, um, intimacy skills of ex Brody Jenner.

She said things were "vanilla."

In most translations, that equals boring.

After a breakup, some people release all a relationship's secrets...even the harmful ones.

Other people stay mum -- regardless of the circumstances.

Tell me: If you keep a "don't kiss and tell" rule, do you feel comfortable breaking it once your relationship has ended?
